The 2018/19 season will bring huge changes at Arsenal, with Unai Emery having been appointed as the club's new head coach.

The Spaniard was selected by chief executive Ivan Gazidis, head of recruitment Sven Mislintat and head of football relations Raul Sanllehi, as Arsene Wenger's successor and the signs are he will shake things up in north London.

He is known as a coach who demands incredible work ethic from his players, he is also known for his attention to detail on the training ground.

Having been officially unveiled, Emery has already got down to work with Mislintat and Sanllehi building what Arsenal hope will be a squad capable of competing again at the top of English football.

So how could Arsenal look under Emery on the first day of the 2018/19 season? We take a look.

The formation

Emery is very much a 4-2-3-1 manager - It’s a formation that served him well at Sevilla and at Valencia before that. In Paris he set the team up more as a 4-3-3, but mainly due to personal.

At Arsenal, however, the Spaniard is expected to go with the 4-2-3-1 formation that he used in Spain. It’s system that is not unknown at the Emirates as Arsene Wenger often used it, with Aaron Ramsey and Granit Xhaka the midfield pairing in front of the defence.

New signings

It’s clear from the process Arsenal have gone through to appoint the new manager that Emery will not have total say in the club’s transfer business.

There aren’t many managers who would be happy with that, but Emery worked under similar circumstances at Sevilla when Monchi was pulling the strings as technical director.

At Arsenal, Sven Mislintat will be in charge - but Emery will still have his say when it comes to bringing players in.

Having already signed Bernd Leno, Stephan Lichtsteiner and Sokratis ahead of next season, it looks like Mislintat is already on the case of adding further additions, with the club working on a deal to bring in Caglar Soyuncu from Freiburg.

But how the midfield operates is always key to Emery’s sides and so bringing in at least one new face to bolster that area will be a priority.

Arsenal had been interested in Max Meyer, but a move to Marseille could be in the pipeline. Grzegorz Krychowiak is a player Emery knows well. He was a key part of his Sevilla side at the base of the midfield and then followed the manager to Paris.

Jean Michael-Seri meanwhile remains a target, but his arrival could depend on what happens with Aaron Ramsey during the next couple of months, given he is just about to enter the final year of his contract.

There are reports that Emery wants to build his side around the Wales international, but the club must first get the midfielder to agree a new deal if he is to do that - something Ramsey has yet to show any real sign of wanting to do.

Adding some width

If Mesut Ozil is played in his favoured No.10 role behind Pierre-Emerick Aubameyang, then Arsenal really do need to add some width to their attack during the off-season.

Henrikh Mkhitaryan will start on the right of the three behind Aubameyang and then there is a gap to fill on the left hand side.

Alex Iwobi could be an option, as could Danny Welbeck. But if Arsenal are to improve and mount a challenge on the top four a least, more quality is needed on that side.

Links to Ousmane Dembele continue, but that deal would only be realistic if Barcelona allow the French midfielder out on loan for the season.

Julian Draxler, a player Emery signed for PSG, could be an option and could be available on loan or even for a workable fee given the French champions’ need to adhere to financial fair play regulations.

There is of course the possibility of Aubameyang lining up on the left of the three, as he did at times last season, with Alexandre Lacazette handed the central striking role

The game plan

While a 4-2-3-1 system will not be unfamiliar to Arsenal, the style of play that Emery looks to adopt could be.

Over the years Arsenal are a team who have looked to dominate possession, a team who attempt to wear down the opposition by keeping the ball and moving it across the pitch with patience.

But Emery is a manager who likes to play on the counter attack. His teams don’t tend to be ones that take too many risks. They instead look to break and react quickly to any mistakes that hand them the initiative.

With players like Aubameyang and Mkhitaryan in the squad already, however, that could work out well for Arsenal.

The losers

It’s impossible not to look ahead to next season and again think that Alexandre Lacazette may struggle for regular game time.

Although Aubameyang filled in well on the left at times towards the end of the last campaign, he did not come to Arsenal to play as a wide attacker.
